Technical Report v1.9.1: Visual Failure Fingerprint Plot for Upscayl High-Fidelity and Upscayl Digital-Art — Supplement to Technical Report v1.9

Supplement to Technical Report v1.9.This document supplements DOI 1.9 of the Merutan Theory series. It provides a rendered Failure Fingerprint (Δμ,Δσ) diagram for the two models verified in DOI 1.9's live SQL execution videos — Upscayl High-Fidelity and Upscayl Digital-Art — using the exact `delta_mu` and `sigma_stat_A`-derived `delta_sigma` values reported and verified therein, plotted relative to the theoretical critical points μc, σc established in DOI 1.0. No new database queries or values are introduced; this report adds only a visual rendering of already-verified numbers and two elementary trigonometric derivations (axis angle and inter-vector angle) computed directly from them, consistent with the diagrammatic presentation style used elsewhere in the Merutan Theory series.
